The duration of the Particle System in seconds.
You can only set this property when the Particle System is not playing.
using UnityEngine; using System.Collections;
[RequireComponent(typeof(ParticleSystem))] public class ExampleClass : MonoBehaviour { private ParticleSystem ps;
void Start() { ps = GetComponent<ParticleSystem>(); ps.Stop(); // Cannot set duration whilst Particle System is playing
var main = ps.main; main.duration = 10.0f;
ps.Play(); } }
